A 28-year-old patient has decided to use the patch contraception. The nurse is educating her on the best site to use. Where is the best place to put the patch? Select one that does not that apply.

Correct Answer: C

Rationale: The best sites for applying the contraceptive patch are the buttocks, arm, and leg. These areas have sufficient fat and are away from areas that might rub off the patch. Choice B (Neck) is incorrect as the neck is not recommended for patch application due to the potential for irritation and the high blood flow area. Choice C (Breast) is not recommended because the breast tissue may affect the adhesion of the patch.

Correct Answer: C

Rationale: Depo-Provera can cause irregular bleeding patterns, including spotting or no bleeding at all. Choice A is incorrect because Depo-Provera needs to be administered every 3 months, not every 5 months. Choice B is incorrect as weight gain is more commonly associated with Depo-Provera, not weight loss. Choice D is incorrect as Depo-Provera can be used regardless of whether the woman has been pregnant before.

Correct Answer: B

Rationale: The IUD may contain metal components, and it's crucial to check for any metal allergies before placement. Choice A, family history of heart disease, is not directly related to IUD use. Choice C is incorrect because previous IUD insertion is not as crucial as identifying an allergy to the materials in the IUD. Choice D is incorrect because hypertension is not a contraindication for IUD use, though it should be monitored.

Correct Answer: B

Rationale: Birth control pills primarily work by preventing ovulation, thereby inhibiting the release of eggs for fertilization. Choice A is incorrect because birth control pills do not directly block sperm; they prevent ovulation. Choice C is partially correct but is not the main mechanism, as the primary function is to prevent ovulation. Choice D is incorrect because birth control pills do not alter the size of reproductive organs.

Correct Answer: A

Rationale: Emergency contraception is most effective when taken within 72 hours of unprotected sex. Choice B is incorrect as it is not as effective after 5 days. Choice C is incorrect because emergency contraception works primarily by preventing ovulation, not by preventing implantation. Choice D is incorrect because most emergency contraception methods are available over the counter.
